OIL-WASTE PRESS.

SPECIFICATION forming part of Letters Patent No. 769,015, dated August 30, 1904.

Application led October 27, 1903. Serial No. 178.741. (No model.)

To a/ZZ Loh/071e it may concern.-

Be it known that I, ADAMS T. PEIRCE, a citizen of the United States, and a resident of Dover, in the county of Straiford and State of New Hampshire, have made a certain new and useful Invention in Oil-VVaste Presses; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a perspective view of the invention. Fig. 2 is a central longitudinal section of the same.

The invention relates to presses to recover oil from cotton-waste and for expressing liquid from other material; and it consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings the letter a designates a cast-metal tank, which is supported on legs 4 and has a tapering or Haring chamber a. The bottom of the tank is indi.- cated at c, and it is provided with a discharge at d, which may have a valve. Around the base of the tank on the-inside is secured the annular shoulder or ledge e, on which rests the perforated-steel press-bottom f, which is removable. This perforated press-bottom is located a short distance above the tank-bottom c. To the sides of the tank are secured the uprights or arms g, which extend above the top of the tank sufficiently to. allow for the removal of the follower in the manner hereinafter set forth. Within the tank is a removable sheetmetal can z, which corresponds in shape to the tank. This can rests upon spacing-lugsf/ of the false bottom f and is centered within the tank-chamber by the tapering walls of said chamber, a space being at the same time left between the sidewalls of the tank and can. This can is of greater height than the tank, extending upout of the same by the portion 71;, which is imperforate. Below the portion the can is perforated in its bottom and side wall. The uprights or arms g extend about half-way up the sides of that. portion of the can which projects above the of the follower which works in the can.

tank, and to their upper ends are connected the cross-head Z, having downwardly-bent end portions m, said cross-head being provided with a central threaded aperture j), forming the bearing for the threaded stem .sl To the upper end of the stem s is secured the cross-head o, having two bearings w in line with each other for the reception of the handle-lever e, which is removable and may be of any desired length.

The cross-'head 1 is pivoted at the lower end of one of its downwardly-bent arms to the upper end of one of the uprights g at a point on about midway of the top of the receptacle /b and the bottom of the follower t, while the lower end of its opposite arm is connected to the upper endl of the other upright by a key g. This key being removed, the bent bearing-bar can thus be turned upward and laterally in such wise as to withdraw the follower from the can suiiiciently for charging the latter with' the cotton-waste. Then the follower is replaced in position and the bent bearing-bar keyed down to the holding upright. The screw then being worked by the lever causes the follower', which is pivoted to said stem, to move downward with great force. The oil expressed from the waste passes through the side and bottom of the can and through the steel bottom into the receptacle formed by the bottom of the tank, whence it may be withdrawn through the discharge. Then the key being removed from the bent bearing-bar the -latter is turned upward laterally, as above described, withdrawing the follower, for which operation it is not necessary to turn the stem back. The can, with the pressed waste, can then be lifted out of the tank and the waste discharged, thus saving time and labor in the work.

Having described the invention, what AI claim, and desire to secure by Letters Patent,

In a liquid-expressing press. the combination, with the outer tank having a tapering IOO 10 about midway of the top of Said can and the follower when depressed, and a detachable Connection Witli the other of said uprights, and a handle-lever upon said Stem, Substantially as specified.
